Objectives: The aim of this study was to analyze the association between energy sources, fiber and mineral intake, and the number of existing permanent teeth in adults aged 55-84 years from the 5th Korea National Health and Nutrition Examination Survey (KNHNES) (2010-2012). Methods: The subjects included 6,763 people who received oral examinations and answered questions on household income, smoking status and diet. We estimated the number of existing permanent teeth and food intake according to age group, sex, household income, and smoking status. A complex samples general linear model was applied to analyze the effect of nutrient intake on the number of existing permanent teeth adjusted for sex, household income, smoking status, and food intake. We calculated the mean intake of nutrients related to the number of existing permanent teeth in each tooth group. Results: The reduction in the number of existing permanent teeth correlated with an increased carbohydrate intake and a decreased potassium intake. The carbohydrate intake was lower in subjects with 25 or more teeth than that in subjects with 9 or less teeth. Potassium intake was higher in subjects with 20 or more teeth. Conclusions: The number of existing permanent teeth showed a negative correlation with carbohydrate intake and a positive correlation with potassium intake. We should reduce carbohydrate intake and increased potassium intake from fruits and vegetables to prevent systemic disease caused by tooth loss.

Objectives: The aim of the study was to analyze the factors related to the illegal dental treatment experience(IDTX) among Korean adults. Methods: The raw data for the analysis of IDTX among Korean adults were obtained from the datasetof the Fourth Korea National Health and Nutrition Examination Survey conducted in 2007-2009. Stratifiedweighted subjects aged ≥45 years were selected according to region by using clustered samplingmethods. In total, the data of 9,254 subjects, who participated in the interview and dental examinationsrelated to the experience of illegal dental treatments, were analyzed using chi-square test, general linearmodel, and logistic regression analysis with complex sampling design by considering demographicand socioeconomic variables (age, gender, region, educational level, household income, and medicaland dental delivery system) as well as oral status variables (prosthesis and number of natural remainingteeth). Results: IDTX rate was <10% among adults aged 35-44 years or below. However, it increased to 15%among adults aged 45-54 years and was >30% among adults aged ≥65 years. The age group with ahigh IDTX rate coincided with the age group with a high number of lost teeth. Most of the IDTX caseswere presumed to be prosthetic treatments. The model comprising demographic, socioeconomic, andoral status variables had the highest explanation power. Significant variables were educational level,household income, prosthesis status, and number of remaining teeth. Women and persons under themedicaid system were more likely to undergo illegal dental treatments. Conclusions: Comprehensive prosthetic treatments are suggested to be included in the care servicesof the national health insurance and medicaid system to reduce the number of illegal dental treatments.

국어과 교육과정과 『생활국어』 교과서의 관계성에 관한 비판적 고찰: 7,8,9학년의 듣기,말하기 영역을 중심으로

박형준 ( Hyung Jun Park ),전은주 ( Eun Joo Jeon ) 경북대학교 중등교육연구소 2008 중등교육연구 Vol.56 No.3

이 논문의 목적은 개정된 국어과 교육과정에 적합한『국어』교과서 개발 담론을 생성하기 위해서『생활국어』교과서의 듣기·말하기 영역을 중심으로 제7차 국어과 교육과정과『생활국어』교과서의 내용 관계성 여부를 비판적으로 고찰하는 데 있다. 『생활국어』교과서는 여러 가지 장점에도 불구하고, 제7차 국어과 교육과정의 내용을 적절하게 반영하지 못했다는 한계를 지니고 있다. 이에 이 논문에서는 제7차 국어과 교육과정의 7, 8, 9학년 듣기·말하기 영역을 중심으로 『생활국어』교과서와의 관련 양상을 비판적으로 분석하였다. 관계성 분석을 위한 기준은 목표 및 내용 반영의 적절성 여부와 교수·학습 방법 및 평가 내용의 반영성 여부이다. 이 기준을 바탕으로 제7차 국어과 교육과정의 듣기·말하기 영역과 『생활국어』 교과서 듣기·말하기 단원의 관련 양상을 고찰한 결과, (1) 교육과정 내용이 교과서의 단원 목표 및 내용으로 반영되는 정도는 매우 높았으나, 표면적인 반영 외에 교육과정 내용과 단원 목표 및 내용 사이의 연계는 적절하게 이루어지지 못했다는 사실을 확인할 수 있었으며, (2) 교육과정의 교수·학습 방법 및 평가 내용이 교과서에 실제성 있게 반영되지 못했다는 사실을 확인할 수 있었다. This study analyzed the connection between listening-speaking of Korean language curriculum for the 7th, 8th and 9th grades and the ``Korean Language in Practice`` Textbook in terms of ``proper reflection of the purpose and contents`` and ``reflection of the teaching-learning methods and assessment contents``. As a result, the contents of Korean language curriculum in each grade was highly reflected by the unit objectives and contents in the ``Korean Language in Practice`` Textbook. However, the reflection score, on the surface, or reflectivity of the curriculum contents does not guarantee a proper connection between the contents of Korean language curriculum and unit objectives and/or contents. Besides, the tutorial handbook for ``Korean Language in Practice`` does not provide practical illustrations and materials for teaching-learning contents, although the tutorial should reflect them as suggested in the Korean language curriculum. Solution to these problems will be as follows; (1) a new textbook for the Revised Korean Language Curriculum should not simply reflect the curriculum itself but consider the suitability of the curriculum contents, objectives/contents of a unit, and finally contents of an integrated unit. (2) Listening-speaking, among various fields of Korean language education, in particular, emphasizes the context and authenticity of a discourse. Therefore, proper illustrations and explanations should be provided for teaching-learning methods, assessment plan, and contents of assessment education.

Objectives: Diagnosis of dental caries is based on the dentist’s observation and subjective judgment; therefore, a reliable and objective approach for diagnosing caries is required. Intraoral camera images combined with deep learning technology can be a useful tool to diagnose caries. This study aimed to evaluate the accuracy of the VGG-16 convolutional neural network (CNN) model in detecting dental caries in intraoral camera images. Methods: Images were obtained from the Internet and websites using keywords linked to teeth and dental caries. The 670 images that were obtained were categorized by an investigator as either sound (404 sound teeth) or dental caries (266 dental caries), and used in this study. The training and test datasets were divided in the ratio of 7:3 and a four-fold cross validation was performed. The Tensorflow-based Python package Keras was used to train and validate the CNN model. Accuracy, Kappa value, sensitivity, specificity, positive predictive value, negative predictive value, ROC (receiver operating characteristic) curve and AUC (area under curve) values were calculated for the test datasets. Results: The accuracy of the VGG-16 deep learning model for the four datasets, through random sampling, was between 0.77 and 0.81, with 0.81 being the highest. The Kappa value was 0.51- 0.60, indicating moderate agreement. The resulting positive predictive values were 0.77-0.82 and negative predictive values were 0.80-0.85. Sensitivity, specificity, and AUC values were 0.66-0.74, 0.81-0.88, and 0.88-0.91, respectively. Conclusions: The VGG-16 CNN model showed good discriminatory performance in detecting dental caries in intraoral camera images. The deep learning model can be beneficial in monitoring dental caries in the population.

The study of Anthropological linguistics, which analyses language factors with the possibility of the practical use and a picture of language immanent in the consciousness of human being, has been suggested as a tendency of the research of Russian study. All people, who have the type of practical apparatus making basic diagram and doing communication in terms of the language structure of one-self, express one`s self thinking by the mandate psychological language and then use practical language material. As it is proved through the many study of structural linguistics, the system of vocabulary can be expressed by the paradigmatic relation of the union and replacement of the word, the syntagmatic relation of language factors composed the expressed sentence by speaking and writing and the derivative relation of the word. As "lexicosemantic field music" is analyzed by the data of ideographical dictionary in this thesis, it suggests the type of the possibility of the practical use and the system of vocabulary involved the language consciousness of modern Russian people. The mutual relation of lexical words as a study about the type of language, which proposes the type of the general use possibility of language, should continue in the level of entire language composed one language beyond the scope of lexicosemantic field limited in a field for Russian scholars and foreigners who study Russian language.

Streptococcus sp. JEJ - 6에 의한 가용성 전분으로부터 L - Lactic Acid 생성에 관한 연구

조영배(Young-Bae Jo),전은주(Eun-Joo Jun),백형석(Hyung-Suk Baik),전홍기(Hong-Ki Jun) 한국식품영양과학회 1998 한국식품영양과학회지 Vol.27 No.3

상당수의 젖산 생성 균주가 알려져 있지만 실제로 L-Lactic acid를 생성하는 균주는 단지 몇 균주에 지나지 않는다. 그 중에서도 공업적으로 L-lactic acid를 생산하기 위해 이용되는 젖산균은 homofermenter이어야 하며 이러한 조건을 만족하는 균주는 Streptococcus속과 일부 Lactobacillus속의 균주만이 알려져 있을 뿐이다. 전분질의 곡물이 젖산을 생산하기 위한 원료로서 주로 사용되는데, 전분의 분해는 젖산균이 일반적으로 가지고 있는 성질이 아니므로 전분을 이용하지 못하는 젖산균을 공업적 발효균주로 이용할 경우 전분을 당화 시켜 발효기질로 이용하거나 병행복합발효법으로 당화와 발효를 병행하는 방법을 이용하는 등의 불편한 점이 있다. 따라서 직접 전분을 이용해 젖산을 생성하는 균주를 분리 하여 이러한 균주를 L-lactic acid 생산균주로 이용한다면 더 간단하고 안정적으로 순수한 젖산을 생산해낼 수 있을 것이다. 이러한 목적으로 본 연구에서는 전분이 기질로 첨가된 김치를 분리원으로 사용하여 상기의 목적에 부합되는 균주를 분리해 냈으며, 분리균주의 배양적, 형태학적 및 생화학적 성질을 검토하여 Streptococcus sp. JEJ-6으로 동정하였다. L-Lactic acid를 생성하는 분리균주인 Streptococcus sp. JEJ-6의 생육 최적 조건과 L-lactic acid 생산 최적 조건을 검토한 결과, 0.1% NaCl, pH 7.0, 37℃, 1% peptone, 0.5% yeast extract가 첨가된 배지에서 균의 생육도와 L-lactic acid 생산량이 모두 높았다. 각 탄소원별로 D와 L-lactic acid 생산성을 비교, 검토한 결과 실험에 사용한 모든 탄소원들에서 L-lactic acid를 선택적으로 생성 하여 높은 광학 순도의 L-lactic acid를 생산하는 것이 확인되었다. 그리고 L-lactic acid 생성에 관여하는 효소인 lactate dehydrogenase를 전처리하여 성질을 검토한 결과 LDH의 NAD 의존성 활성의 최대 활성 pH는 pH 8.5였으며 homofermenter들의 LDH의 최적 활성 pH가 7.8~8.8이라는 보고와 일치하였다. 반면 NAD 비 의존성 활성의 최대 활성 pH는 7이었다. The strain producing L-lactic acid from starch was isolated from kimchi. The isolated strain was identified as a homofermentative Streptococcus sp. through its morphological, cultural, biochemical characteristics, and named Streptococcus sp. JEJ-6. Lactic acids are of two types, one L-specific and the other D-specific form in a stereospecific form. Streptococcus sp. JEJ-6 produced selectively L-lactic acid from all of the tested carbon sources. The optimum conditions for the L-lactic acid production from the isolated microorganism were determined. For the maximum yield of L-lactic acid from Streptococcus sp. JEJ -6, the cell should be harvested at the early stationary phase, and the growth temperature, pH, and NaCI concentration should be 37℃, pH 7.0 and 0.1%, respectively. 4% Soluble starch as substrate and organic nitrogen sources such as peptone and yeast extract should be used for the best yield. The optimum pH of the nicotinamide adenine dinucleotide(NAD)-dependent and NAD-independent lactate dehydrogenase(LDH) activities was pH 8.5 and pH 7.0, respectively.
